ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Umm unless this is a homework, you could get it done easier if you used the ncurses library, for example. It's got some handy functions for drawing windows, panels and overall printing things to specific positions on the screen. But if this is a homework, then you probably can't go there.. (and should anyway mention if this is a homework).
Sorry, I didn't really look closely at your code. I see you're working with the Windows console functions. I don't have access to a Windows dev environment at the moment, but I think you just have a precedence problem:
"!" has higher precedence than ">" so your loops weren't running at all. It might be better to rewrite the condition as
for (x=0; x <= (tmp.right-tmp.left); x++)
By the way, you really should try to give your variables more meaningful names than "tmp". And spaces between operators can also look a lot nicer.
